This got me to thinking (Warning! Danger, Will Robinson!) We are getting a z/800 2066-0A2 with an OSA card + 1 IFL and z/VM. I wonder if it would be more efficient to allow a Linux/390 image to "own" the OSA card and act as a gateway for the OS/390 images. It would connect to all other images, Linux and OS/390, via hipersockets. That is all that this Linux system would do. I'm looking at way to "offload" OS/390 work onto a Linux image. So, is there less CPU overhead by using hipersockets than using the OSA card directly? Or would it be a "wash" since they are both QDIO devices?
I image either would be superior, in terms of CPU overhead, to using our Cisco 75xx with a CIP card since the Cisco requires "standard" I/O. We won't replace the Cisco, because we use it along with Rumba to do all the 3270 emulation. I don't want to use TN3270 emulation on the CPU itself. -- John McKown Senior Technical Specialist UICI Insurance Center Applications & Solutions Team +1.817.255.3225 > -----Original Message----- > From: Mark Kliner [mailto:[EMAIL PROTECTED]] > Sent: Tuesday, August 20, 2002 12:34 PM > To: [EMAIL PROTECTED] > Subject: Re: Hiper Socket > > > Have you seen the zSeries HiperSockets Redbook? > > http://www.redbooks.ibm.com/pubs/pdfs/redbooks/sg246816.pdf > > > Mark Kliner > Systems Programmer > Vision Service Plan > Rancho Cordova, CA
